LAY ROCKER-SHAFT BEARING FOR LOOMS.

Application filed January 16, 1924. Serial No. 686,520.

To all ill/1011b 1'2- 7II(.(. I/ concern:

Be it known that l ALUNZO E. Rnoanns, a citizen of the United States, residing at llopcdale, in the county of \Vorcester and State of Massachusetts, have invented an Improvement in Lay Rocker-Shaft Bearings for Looms, of which the following description in connection with the accompanying drawings is a specification, like characters shaft bearing of anti-friction type which primarily supports the entire weight of the lay rocker-shaft and its load and may be readily adjusted in an upward andv downward direction to maintain the parts in proper operative position. with the present invention, the anti-friction bearing for supporting the weight of the lay rocker-shaft and its load is formed'as a frame adjustably connected to the side frame of the loom and adjustable in an upward direction to maintain the lay rocker-shaft and anti-friction devices in proper supporting position regardless of wear. The suspension framefor the anti-friction devices, preferably formed as rollers, consists of sustaining leg portions between which is an anti-friction roller supporting cage disposed below the lay rocker-shaft, and in order to relieve the lay rocker-shaft itself from any wear due to its oscillating motion, the present invention contemplates providing the .layrockershaft with a collar having a flange portion below the lay rocker-shaft torest upon theanti-friction'devices.

The various features of novelty and newcombination of parts Will best be made clear.

from the following description and the accompanying drawings of one good form of In accordance the invention, the scope of which will be definitely defined by the claims.

In the drawings:

Fig, l is a perspective view of one side of the loom at the lower portion thereof,

showing one end portion of the lay rocker shaft as provided with the present invention;

Fig. 2 is a side elevation of the lay rocker sha ft hearing viewed from the inside of the loom frame, the lay rocker-shaft itself being shown in section; and

Fig, 3 is a section on the line 3-3 of Fig. 2.

The loom is provided as usual with two side frames 1, one at each side of the loom, between which extends the lay rocker-shaft 2, and as usual the lay rocker-shaft extends through the side frames and its outer portion has secured thereto a shoe for the picker motion. Secured to and extending upwardly from the lay rocker-shaft are the lay swords 3, one of which only is shown, it being understood that the opposite side of the lay rocker-shaft has another lay sword secured thereto.

Each of the side frames 1 of the loom has an opening 4 through which the lay rockershaft 2 extends, and in the present instance the loom frame has secured to the outer side thereof the main hearing or bushing member 5, the bushing-6 of which extends inwardly through the opening 4 of the adjacent side frame. The main hearing or bushing memher 5 is secured to the loom frame by suitable bolts 7 which pass through the openings 8, enlarged laterally to permit the hearing or bushing member 5 to be adjusted towards and from the front of the loom.

()n the outwardlv extending portion of the .lay rocker-shaft 2 at each side of the loom comprising the two leg portions 12 between which extends the roller bearing cage 13 in which rest the rollers 14: or like anti-friction devices. The rollers 14, as shown, are held in the cage 13 by the side projecting portions 15 of the roller cage. At their upsion frame 12 and the roller cage below the ,lay rocker-shaft may be adjusted in a substantially vertical direction. -As shown, each of the adjusting screws 18 is provided with a lock nut 19 whereby when the suspension frame has been properly adjusted the parts may be locked in the adjusted position.

Between the leg portions 12 of the suspension frame and the roller cage 13 the suspension frame has side extending por-- tions 20, Fig. 2, each of which is provided with the vertically extending openings 21 bearing through which project the screws 'or bolts' 7, hereinbefore described as securing the or bushing 5 in its laterally adjusted position.

Between the lay swords 3 and the adjacent side frame ofthe loom, the lay rocker-shaft is provided with a collar'22 which may be secured thereto in fixed position by the headless set 'screws 23. The collar 22 is provided on its under-portion with a widened flange 24 which rests upon the rollersin the underlying roller cage 13 and such flange preferably extends over the rollers to exclude therefrom. lint, dirt and other foreign substances.

As shown in the present instance of the invention, the collar 22 is secured to the lay rocker-shaft between the adjacent lay sword 3 and'the end of the bushing or hearing 6 through which the lay rocker-shaft extends,

- tion.

The cage 13 as shown is preferably formed the construction beingsuch that the parts areassociated in fixed and unvarying posias a segment or part of an annulus, and

similarly the flange 24 of the collar 22 is formed as a segment which provides an enlarged surface bearing rest-ing upon the antifriction rollers 24. v

In the present embodiment of the i'nven tion the suspension frame is shown as on the inside of the adjacent loom side frame, while'thebearing member or bushin 5 is on the outside of the same loom side rame, and while this is preferred, the invention is not necessarily limited to this disposition of theparts which of course might be reversed within the true scope oftheinvem' tion.

ing 6, which as hereinbefore described, may

1,ese,e11

be adjusted laterally and also vertically by reason of the slots in the main side frame, serve to laterally position the rocker-shaft bearing 2 in the side frames, or define its position towards and from the front of the loom, while the suspension frame and the anti-friction devices support the entire weight of the lay rocker-shaft and its load, so that b the simple adjustment of the suspension rame all wear may be readily taken up andthe lay rocker-shaft, lay and other parts he maintained in their proper operative position. From the construction described it will be apparent that the roller bearing being positioned below the lay rocker-shaft and adjustably connected to the adjacent side frame independent of the bearing or bushing member 5, vertical adjustment of the lay rocker-shaft may be readily accomplished to maintain the lay and other parts in proper operative position,

and if desired the roller cage 13 may be entirely removed from the looin and another substituted in its place without necessitating the removal of the lay shaft or associated arts.
